Question 1

How does the portion calculator estimate my energy needs?

Accepted Answer

It estimates your resting energy expenditure and multiplies it by a physical-activity level (PAL) — the method of the D-A-CH reference values. The result is shown in kilocalories, alongside the matching Ernährungspyramide portions.

Question 2

What values is the calculator based on?

Accepted Answer

The joint D-A-CH reference values for energy intake (derived in 2015, still current) and the resting-energy formula the DGE uses for adults. We invent no targets of our own — we reproduce the published guide values.

Question 3

What is a PAL value?

Accepted Answer

PAL stands for “physical activity level” and describes how active a day is. Mostly seated work is about 1.4–1.5; walking and standing work 1.8–1.9. Regular sport can add roughly 0.3.

Question 4

Does the calculator use kilocalories or kilojoules?

Accepted Answer

Kilocalories (kcal) — the unit the DGE publishes. Kilojoules (kJ) can be derived from it (1 kcal = 0.004184 MJ) but are not the official figure.

Question 5

Does the calculator replace dietary advice?

Accepted Answer

No. The results are general guidance based on population reference values and do not replace individual advice from a doctor or dietitian — especially in pregnancy, breastfeeding or illness.
